Description

Technical Field

[0001] This utility model relates to the field of concrete slab technology, and in particular to an assembled concrete slab. Background Technology

[0002] In the field of construction engineering, traditional concrete construction has long dominated. On-site concrete pouring requires the erection of complex formwork systems. From setup to dismantling, on-site pouring operations are easily affected by weather conditions. Rain, high temperatures, strong winds, and other severe weather can interfere with construction progress and concrete quality, leading to frequent problems such as surface defects and uneven strength. The construction cycle is also extended due to the long curing time of concrete. From pouring to reaching the design strength, it often takes several days or even weeks, slowing down the overall project delivery pace. Existing prefabricated concrete slabs have complex designs that not only consume a large amount of timber, steel, and other formwork materials, but also rely heavily on skilled carpenters, resulting in high labor costs. Therefore, improvements are needed to address the above problems. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a modular concrete slab.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a modular concrete slab, comprising a concrete slab body, wherein a fixing groove is provided in the middle of both sides of the concrete slab body, and a fixing steel plate is installed in the fixing groove at the connection of two concrete slab bodies, wherein the fixing steel plate has a cross-shaped cross section.

[0005] Preferably, a positioning groove is vertically opened through the connection between two concrete slabs on the same side, and a first fixing steel column is provided at the upper and lower ends of the positioning groove. Multiple first fixing steel columns are installed on both sides of the top and bottom surfaces of the fixing steel plate, and the positioning groove is filled with first fixing concrete.

[0006] Preferably, a reinforcing rib is provided at the unconnected part of the fixing groove. The reinforcing rib is triangular and placed in the fixing groove. An L-shaped fixing plate is fixed to the outer side of the vertical plane of the reinforcing rib. Fixing holes are provided at both ends of the L-shaped fixing plate. Fixing bolts are provided in the fixing holes. The L-shaped fixing plate is connected to the concrete slab through the fixing bolts.

[0007] Preferably, two through holes are equidistantly provided at the center of the front end of the concrete slab, and a conduit is sleeved inside the two through holes. Additionally, mounting holes are provided on both sides of the center of the top surface of the concrete slab, and a conduit is installed in the mounting holes and connected to the conduit.

[0008] Preferably, T-slots are provided on both the front and rear ends of the concrete slab, and I-shaped steel is installed in the T-slots.

[0009] Preferably, two second fixed steel columns penetrate both ends of the top surfaces of the two I-shaped steel sections, and the upper and lower ends of the T-shaped groove are filled with second fixed concrete.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model facilitates the connection and fixation between concrete slabs through the cooperation of I-beams and the second fixed concrete, thereby improving the overall structural stability of the concrete slabs and enabling the strengthening of the structure between the concrete slabs. Furthermore, the cooperation between the concrete slabs and the fixed steel facilitates the installation and fixation of the concrete slabs, improving the installation efficiency of the concrete slabs and enabling the convenient and quick assembly of the concrete slabs. Ultimately, it solves the problem that complex designs not only consume a large amount of timber, steel and other template materials, but also rely heavily on skilled carpenters, resulting in high labor costs.
